• 9f83e45eb   [PATCH] Fix current_io_context() vs set_task_ioprio() race ... Browse Code »

  I know nothing about io scheduler, but I suspect set_task_ioprio() is not safe.

  current_io_context() initializes "struct io_context", then sets ->io_context.
  set_task_ioprio() running on another cpu may see the changes out of order, so
  ->set_ioprio(ioc) may use io_context which was not initialized properly.

  From include/linux/sched.h:

  * Careful: do_each_thread/while_each_thread is a double loop so
  * 'break' will not work as expected - use goto instead.

• a1836a42d   [PATCH] SELinux: Add security hook definition for getioprio and insert hooks ... Browse Code »

  Add a new security hook definition for the sys_ioprio_get operation. At
  present, the SELinux hook function implementation for this hook is
  identical to the getscheduler implementation but a separate hook is
  introduced to allow this check to be specialized in the future if
  necessary.

  This patch also creates a helper function get_task_ioprio which handles the
  access check in addition to retrieving the ioprio value for the task.

• 03e680606   [PATCH] lsm: add task_setioprio hook ... Browse Code »

  Implement an LSM hook for setting a task's IO priority, similar to the hook
  for setting a tasks's nice value.

  A previous version of this LSM hook was included in an older version of
  multiadm by Jan Engelhardt, although I don't recall it being submitted
  upstream.

  Also included is the corresponding SELinux hook, which re-uses the setsched
  permission in the proccess class.

  - Make ioprio syscalls return long, like set/getpriority syscalls.
  - Move function prototypes into syscalls.h so we can pick them up in the
  32/64bit compat code.

• 22e2c507c   [PATCH] Update cfq io scheduler to time sliced design ... Browse Code »

  This updates the CFQ io scheduler to the new time sliced design (cfq
  v3). It provides full process fairness, while giving excellent
  aggregate system throughput even for many competing processes. It
  supports io priorities, either inherited from the cpu nice value or set
  directly with the ioprio_get/set syscalls. The latter closely mimic
  set/getpriority.

  This import is based on my latest from -mm.
